Что такое WinAPI

Например так:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Runtime.InteropServices;

namespace WindowsFormsApplication1
{
    public class MonitorPower
    {
        private const int MONITOR_ON = -1;
        private const int MONITOR_OFF = 2;
        private const int WM_SYSCOMMAND = 0x0112;
        private const int SC_MONITORPOWER = 0xF170;
        private const int HWND_BROADCAST = 0xffff;

        [DllImport("user32.dll")]
        private static extern IntPtr SendMessage(IntPtr hWnd,
                                                 uint Msg,
                                                 IntPtr wParam,
                                                 IntPtr lParam); //это WinAPI функция


        [DllImport("user32.dll")]
        private static extern IntPtr GetForegroundWindow(); //это WinAPI функция

        public static void MonitorOff()
        {
            IntPtr foregroundWindow = GetForegroundWindow();
            if (foregroundWindow == IntPtr.Zero)
                foregroundWindow = (IntPtr)HWND_BROADCAST;

            SendMessage(foregroundWindow, WM_SYSCOMMAND, (IntPtr)SC_MONITORPOWER, (IntPtr)MONITOR_OFF);
        }

        public static void MonitorOn()
        {
            IntPtr foregroundWindow = GetForegroundWindow();
            if (foregroundWindow == IntPtr.Zero)
                foregroundWindow = (IntPtr)HWND_BROADCAST;

            SendMessage(foregroundWindow, WM_SYSCOMMAND, (IntPtr)SC_MONITORPOWER, (IntPtr)MONITOR_ON);
        }
    }
}

Большое спасибо вам. А как я могу найти функции, переменнии WinApi? Например
private const int MONITOR_ON = -1;
private const int MONITOR_OFF = 2;
private const int WM_SYSCOMMAND = 0x0112;
private const int SC_MONITORPOWER = 0xF170;
private const int HWND_BROADCAST = 0xffff;
SendMessage(IntPtr hWnd, uint Msg, IntPtr wParam, IntPtr lParam);

ну откуда можно найти полний список?
